SAN ANTONIO WATER SYSTEM

DOS RIOS WRC NON-POTABLE WATER SYSTEM UPGRADES SAWS Job No. 13-6509

SAWS Solicitation No. B-13-072-RA

ADDENDUM No. 2 November 25, 2013

To Bidder of Record: This addendum, applicable to work referenced above, is an amendment to the bidding documents and as such will be made a part of and included in the Contract Documents. Acknowledge receipt of this addendum by entering the addendum number and issue date in the space provided in submitted copies of the proposal. QUESTIONS AND CLARIFICATIONS Q1. Demolition Note 10 on DWG G2 states that contractor is to provide 8’ tall chain link

temporary fencing with black fabric around each project site. Please confirm this note is to be deleted.

A1. Demolition Note 10 will be deleted. The project site is within the secured fence line of

the Dos Rios WRC plant site. SAWS does not require security fencing for this project. Contractor is responsible for securing his equipment, material, etc. through means that he deems necessary.

Q2. General Note 41 states work hours are 8 am to 5 pm. Please confirm contractor is

not limited to those working hours. A2. General Note 41 will be revised to state that allowable Contractor work hours are

Monday through Friday from 7 am to 6 pm. Special circumstances requiring work hours beyond these normal times must be coordinated at least 72 hours in advance with SAWS personnel.

Q3. Dwg M2, General Note 7 refers to performing work on the NPW system will be

restricted to “periods of low NPW system demand”. Please identify approximate time and duration of low demand period.

A3. The period of low NPW system demand is when the belt filter presses (BFPs) are not

operating. The BFPs are typically not running from 6 pm to 6 am. Q4. How long can the NPW system shut down during normal operations?

A4. Any shut down of the NPW pumps will require advance and close coordination with

SAWS Dos Rios WRC Operations Staff. Since the NPW system demands are significantly larger when the belt filter press facility is operating, any shut down of all NPW system pumps will be required to occur when the belt filter presses are not operating. In addition, the elevated storage tank volume of 150,000 gallons will need to be full or nearly full. When the above conditions are met, the time allowed for all NPW pumps to be shut down is estimated to be 2 hours.

Q5. Please provide details regarding lead paint found at the Elevated Storage Tank. A5. A previous report prepared for SAWS contains paint and soil sample information and is

currently posted on the SAWS project website. The report is titled the Dos Rios Elevated Storage Tank – Painting and Rehabilitation Report, Phase A Report, and was prepared in May 2012 by LNV Engineering, Inc. This document is for informational purposes only.

Q6. Please consider providing the contractor with a period of time after the price

proposal submission to prepare final qualifications proposal (ie 24 hours). This will allow contractor sufficient time to tailor the specific demolition procedure to the apparent low subcontractor.

A6. All required information will need to be submitted with the price proposal. Q7. Drawing M3, has a call out, (2/M7) for the 4" Air/Rease vacuum Breaker, However,

there is no detail 2 on drawing M7, are we to use detail 3? A7. Detail No. 3 on Sheet M7 will be relabeled as Detail No. 2. The 2-inch isolation gate

valve in the detail will be modified to a 4-inch gate valve. Q8. Drawing M3, there are expansion joints drawn next to the pump discharges, and

the expansion joint are drawn like "Elastomeric Bellows Expansion Joint (as soon in the details on Sht G3). However, the notes on Sht G3, state, the Bellows Expansion Joints should be Type A or B depending on the specifications...When I looked at the specification 15080, 2.4, E, Rubber Expansion Joints, there is no Type A or B.

A8. The expansion joints between the pump discharge and piping are intended to be the

Rubber Expansion Joints referenced in Section 15080, 2.4, E. References to Type A or B Bellows will be removed from the Elastomer Bellows Expansion Joint description in the Pipe and Fitting Symbols on Sheet G4.

Q9. The specifications for the surge relief valve require the Singer 206-RPS model which

is a flow-through valve. The plans indicate an angle valve body. Please confirm which valve body is required.

A9. The angle valve body is required as described in the specification. The Model number

A1 - 2

does not designate whether the valve is a globe (flow through) or angle valve. Specification Section 15102 and the Schedule of Manufacturers and Suppliers will be revised to also include Cla-Val Model 652-01 as an engineer approved manufacturer.

Q10. Spec. 02527 Polyurethane Coating on Steel or Ductile Iron Pipe, 2.1, Coating

Material B Coating System: Use Type V system...Where is Type V system? I see no type V system in this specification. When I go to Specification 09900 3.7 Protective Coating Schedule, V (on page 11), This system is for concrete sealed floors...

A10. Specification 02527 has been deleted in its entirety because it was redundant to other

specification sections. The coating system for exterior, non-submerged ferrous metals, which includes ductile iron pipe, is specified in Section 09900 3.7.I as amended herein. The interior lining for non-potable ductile iron pipe is specified in section 15020 2.5.B.

Q11. Spec. 02527 Polyurethane Coating on Steel or Ductile Iron Pipe, , I not sure how to

read this specification, it appears you want CORROPIPE II-TX as the DIP coating or this project...however, I'm having a hard time determining if the engineer is requiring the DIP to be painted in the shop or in the field once installed, also keep in mind that existing piping will need to be painted as well...please clarify.

A11. New pipe and pipe supports are required to be coated in the shop. The contractor must

repair coating imperfections prior to final acceptance. Specification Section 02527 has been deleted. Surface preparation and coating specifications for the existing ductile iron pipe is stated in Answer 10, above.

Q12. Specification Section 02527 – Polyurethane Coatings on Steel or Ductile Iron Pipe

requires a special 25 mil polyurethane external coating for steel or ductile iron pipe. However Specification Section 15001, Paragraph 2.4.E.2 requires field paint per Specification Section 09900 which requires a 9 mil total, epoxy paint system.

A12. Specification Section 02527 has been deleted. Section 09900 3.7.I. has been revised to a

required total thickness coating between 21 and 25 mil. Q13. Which system should be used for the coating of steel or ductile iron pipe? A13. Refer to Answer 10 above for clarification of pipe coating specifications. Q14. Ductile Iron Pipe - 15020, , 2.2 A, Sentence three...For Bolted joints, conform

to requirements of AWWA C111; provide minimum 316 stainless steel bolts for restraint joints. We are not quite sure what the engineer is saying here...AWWA C111, 4.6.6 sends us to appendix C, C.1, which calls for ASTM A301 Grade B Bolts & Nuts... But the Clause following the semi-colon state 316 SS bolts for restraint joints...we

A1 - 3

have not restrained joints for DIP for this project unless you consider a Flange Joint a restrained joint. Please clarify the engineers intent, are we to use A307 Grd B bolts & nuts or 316 SS.

A14. All bolts and nuts for restrained joints (and flanged joints) shall be 316 SS. There is a

small amount of buried pipe connecting the hydropneumatic tank to the NPW distribution system. The requirements of AWWA C111 apply except for the substitution ot 316 stainless steel bolts and nuts.

Q15. On page M6, the detail for the Level Control Probe Chamber table contains item #3,

a bronze check valve, but the check valve is not shown in the detail. Please clarify if a check valve is required.

A15. The check valve is not required in the Level Control Probe Chamber and will be deleted

from the legend. Q16. List the permits anticipated for this project. A16. The site is located within the COSA City Limits. Due to the VFD enclosure building size

and function, a COSA building permit is not required. A COSA Plumbing Trade permit is not required. Permits anticipated for this project include, but are not limited to, the following:

1. COSA Demolition Permit 2. TCEQ Waste Permit Division, One-Time Shipment Request for Hazardous or

Class 1 Waste (Lead paint on elevated storage tank). 3. NPDES SWPPP Permit 4. Electrical trade permit, only for the normal distribution replacement/upgrades,

not for low voltage systems. Q17. Outline the parameters that are essential for construction sequencing. A17. Maintain at least two (2) pumps operational (2,000-gpm at 65-psi) at all times with an

emergency power supply and an operational existing elevated storage tank until the new pumps and the hydropneumatic tank are installed. Any interruptions of pump operation shall be limited to 2-hours during periods of low NPW demand (6pm to 6am) and a relatively full elevated tank. New breakers for the VFD building need to be installed early in the process. Demolition of the MCC cubicle components shall occur after new pumps are installed and operational.

Q18. Please clarify where pipe insulation and heat tracing is required.

A1 - 4

A18. Insulate all outdoor exposed piping 4-inches in diameter and smaller, and on larger

pipes, if shown in the Plans, as specified in Section 15180. Sheets E13 and E14 show the instrument and process piping that will be heat traced.

Q19. Provide the as-built drawings for the elevated storage tank and weight of the tank. A19. A set of construction drawings provided by CBI are now posted on the SAWS website for

this project. Sheet 15 shows the depth of the spread footing foundation. Based on the CBI construction drawings, Sheet 15 indicates the weight of the metal components of the tank structure is 118,500 pounds. Contractor is to verify weight, information and data. This is provided for informational purposes only.

Q20. In section 01010, 4a: "Items that are salageable shall be protected and returned to

Saws". Is any part of the elevated water tower to be returned to Saws? If so, what part/parts?

A20. No items on this project will be retained by SAWS. All elevated storage tank materials

including piping and valves will belong to the Contractor. In addition, all equipment removed from the NPW pump station for this project including pumps, motors, piping, valves, strainer, and all appurtenances will belong to the Contractor.

Q21. We see the demo is after much other work. Approx when do you expect to be ready

for, and need the elevated water tower dismantled? A21. The elevated storage tank must remain in service until the new pumps and hydro-

pneumatic pressure system are installed and operating properly. Demolition of the elevated storage tank is anticipated to occur the last month of the project schedule.

Q22. Has a previous asbestos inspection been done? If so, please forward. (many demo

permits require a copy of this). A22. SAWS does not have record of a previous asbestos survey for the elevated storage tank.

The Contractor shall include the cost for providing this survey in the bid item for elevated storage tank demolition.

Q23. Section 01060, P-2 Item H, Soil Sampling. Our experience tells us that soil samples

would vary wildly (10% - 400%) taken today and tomorrow with no activity on site at all. Many engineers and evironmental scientist know this, and thus write their pre / post tolerances much more lenient (for example, four standard deviations or a certain ppm increase).

a. Will you concider relaxing your parameters, which I see as any net increase post over pre will need abated?

A23. Per Section 02060. 3.3.D, paragraph 3, the Contractor is responsible for removal of the

A1 - 5

top six inches of soil within 50 feet of the tank. The soil sampling method defined in Section 01060, H. Soil Sampling, is to determine the material classification for the proper method for top soil disposal and to test site bottom soils. The soils below the 6-inch layer (bottom soils) shall be tested prior to the placement of clean fill. The bottom soils are acceptable if they contain heavy metal concentrations less than the “no action required” concentrations for residential soils. Per the USEPA, the “no action required” concentration for lead in soil is 400 ppm. Additional excavation and disposal may be required if the bottom soils exceed threshold concentrations. Appendix IV of the LNV Report, posted on the SAWS website for informational purposed only, shows a level of 7 ppm lead in site soils from previous test results.

Q24. 02060 Demolition 1.4A: San Antonio noise ordenance, what is your noise

ordanence? what are the hours, etc. A24. The Contractor must comply with the City of San Antonio Noise Ordinance (San Antonio,

Texas Codes and Ordinances, Part II Code, Chapter 21 Offenses and Miscellaneous Provisions, Article III Noise, Division 1. Generally. The web address for the City Municipal Code is:. http://library.municode.com/index.aspx?clientId=11508. .Night hours are considered 10 pm to 6 am Sunday through Thursday and 11 pm to 6 am on Friday and Saturday.

Q25. 02060 1.4D: We are attaching an O.H: from experience, we believe it will be wise

to close the two closest streets for the two day project. (to eliminate spark damage to autos). Will this be allowed?

a. can the streets be blocked as shown for the 2 day demo. b. Are these streets inner water plant streets, and NOT city streets. A25. Both streets fronting the elevated tank can be blocked simultaneously an approximate

distance of 180 feet from the four-way intersection for a period of 2 days as long as the far half of the intersection remains open to the adjoining streets and coordinated with SAWS at least 72 hours in advance of need. These streets are plant streets and carry only plant traffic. Plan Sheet C8 has been revised to show the approximate location of temporary plant road closure.

Q26. 02060-3 1.9B: Containment of Lead based paint- If i read this correctly, you are

laying out 3 options? 1. brush free all loose paint. 2. Entire containment. 3. lower large sections to the ground.

We will choose #3, however the next sentence states containment plan shall be submitted to the engineer for approval. although these plans seem to be written along the lines of our standard methods of operation, we are still taking a huge gamble that the engineer will O.K. this method of opperation/3rd option. Can any assurance be given?

A1 - 6

http://library.municode.com/index.aspx?clientId=11508

A26. The Engineer also prefers the use of Option No. 3. The Engineer will approve the use of

Option No. 3 if the Contractor meets all standard methods of operation and regulatory requirements.

Q27. 02060 3.7 - 16 air quality monitoring: "Two monitors under the supervision of a

CIH". Often, the field tech is an I.H, working for a larger business that has a CIH on staff, will an I.H rather than a CIH suffice?

A27. Yes. For clarification, the field technician must have an Industrial Hygienist (IH) certification and work under the general supervision of a Certified Industrial Hygienist (CIH) staff member.

Q28. Drawing Number M-3, section C calls out a 8 Butterfly Valve Number DR- YYP -

V13 but specification for Gate Valves 15101, 1.2 list the valve as a Gate Valve. Please Advise.

A28. The 8-inch valve on Sheet M3, Section C is a gate valve. The text on Sheet M3 will be

revised. Q29. Drawing Number M-3 show four Air Release / Vacuum Breaker (Combo), three in

the pump discharge (DR-YYP-V01,2,3) which are listed in Specification 15105, however, there is a fourth Air Release / Vacuum Breaker in the 20" Header that is un-numbered.

A29. The fourth air release/vacuum breaker valve has been added to the equipment tags in

Section 15105 1.2.D as DR-YYP-V18. The manufacturer of the air release/vacuum breaker valves shall be as specified in Section 15105, 2.4.A.4.

Q30. Specification 15101, list two gate valves, DR- YYP - V13, DR- YYP - V17. However

we can not find Gate Valve Tag # DR- YYP - V17, we Assume the 12" Tapping Gate Valve at the HydroPneumatic Tank.

Also note, there are several Gate Valves not numbered, (5 ea. 4", 1ea. 16" Tapping Valve). Please Advise.

A30. DR-YYP-V17 is the 12” tapping gate valve. The 4-inch gate valves have been added to

the list of equipment tags in Section 15101.1.2.C. through F. Q31. Spec. 15020 2.5 Coating & Linings...E, b...Provide...in accordance with section

09905...there is no specification 09905.

A31. The above reference to Section 09905 has been deleted. The correct specification references for ductile iron pipe coatings and linings are noted in Answer 10.

PART 1 - GENERAL

1.1 SCOPE SUMMARY

A. Furnish all labor, materials, equipment and incidentals required to upgrade the NPW System Pump Station in its entirety and to demolish and remove the existing 0.15-MG Dos Rios NPW Elevated Storage Tank, as shown on the Drawings, and as specified herein.

1.2 WORK COVERED BY CONTRACT DOCUMENTS

A. The work includes, but is not limited to the following: 1. Install temporary erosion control devices 2. Site preparation including location of above and below grade utilities and demolition of

facilities as noted in the Drawings. Both the Dos Rios NPW System and East Reclaimed Water System (ERWS) must remain in continuous operation for the duration of this project. The project work area contains ERWS piping and conduits which must be protected and/or relocated.

3. NPW Pump Station Upgrade a. Replace three (3) existing vertical turbine pumps. b. Install Variable Frequency Drives (VFD) for each pump and install a controlled

environment pre-cast concrete enclosure. c. Replace all piping including valves, pipe supports, strainer, and appurtenances in the

pipe header to the 20-inch NPW distribution main. Items that are salvageable shall be protected and returned to SAWS.

d. Add a hydro-pneumatic tank pressure system. e. Install electrical system power, monitoring and control systems.

4. Demolition of the existing Dos Rios NPW 0.15-MG Elevated Storage Tank (NPW EST). a. The existing NPW EST shall be demolished including all appurtenances and disposal of

all spoils material in strict accordance with all applicable hazardous waste disposal requirements. Refer to Section 01060 Regulatory Requirements and Section 02220 Demolition.
